Bill Bradbury replied to Tom Mallard's discussion Standard Wall Thermal Upgrade Analysis
"Thanks for the link, this is a great app! We do lime plaster finishes on our historic restorations, so adding hemp is a no-brainer; thanks for the suggestion."

Bill Bradbury replied to Ernest V.F. Hodgson's discussion Combustion Furnace BTU output
"For natural gas, run only the furnace for a given time, mark the dial difference on the meter and multiply the gas used by the heat multiplier for your gas supplier. This will give you a ball park estimate."

Bill Bradbury replied to David Eggleton's discussion Status Reports in the group Considering Permaculture &/or Transition
"It makes me sad to see that in the 2 years this forum has been open, there has been one post and 6 views. If we were discussing the energy value of a fart in the wind, there would be this much activity in 10 minutes! We love to discuss the insides…"

Bill Bradbury replied to Jonathan Bluey's discussion HELP - AIR SEALING a Continuous Stone Interior/ Exterior Wall
"Air sealing a wall like this must be done with a vapor diffusive material or you will get spalled stone faces from sealing materials holding water. I recommend mixing hydrated lime with local clay soils, this is the way they have been sealed for…"

Bill Bradbury commented on Lester Shen's blog post Combi System Animations
"Ben, these animations are great, but they lack real information like; what kind of control system are you using, the second image in the optimal installation hits 85 % efficiency when running optimally, but what happens when the house warms and…"

Bill Bradbury replied to John Poole's discussion Historic Windows: UV and Thermal Transfer in the group Historic Home
"Hi John, I don't internet much either. I install the bottom furring strip in pieces and usually have enough left over from the other 3 sides to piece together the bottom. This is the only time I use that funky PVC wood. I keep the holes small,…"
Dec 11, 2012
Bill Bradbury commented on Lester Shen's blog post Combi System Animations
"After installing several of these systems, I found it difficult to maintain the low return temps necessary for condensing water from the flue gases. Latent heat is the heat that steam gives off when it changes from a higher(vapor) to a lower(liquid)…"

Bill Bradbury replied to Barbara Smith's discussion Eliminating Standing Pilot Light Furnaces
"Yes, a typical annual household heating bill here is about the same, but my client has spent his money on weatherization, so he is saving $600/year. There is no heating appliance that can make that kind of difference. We need to use our common sense…"
Dec 11, 2012
Bill Bradbury replied to Barbara Smith's discussion Eliminating Standing Pilot Light Furnaces
"1) Turn down the gas pressure, that is a crazy big pilot 2) Replacing this cast iron beauty is a lot more complicated than it sounds. Unless the distribution system is also updated, return water temps will be >120F resulting in your new 90%+ mod…"
Dec 11, 2012
Bill Bradbury replied to Barbara Smith's discussion Eliminating Standing Pilot Light Furnaces
"Technology has it's place, but legislating the adoption of new(or in this case not so new) technologies is not the way to reduce energy use. Last week I repaired a 100 year old NG converted coal burner for a client who has spent his money on…"

Bill Bradbury replied to Ronald L. Stevens's discussion How to help new energy pros migrate into our new career as fresh students right out of class
"So glad to hear, good luck!"
Apr 18, 2012
Bill Bradbury replied to Sean Lintow Sr's discussion Drilling B-Vents in the group Best Practices (Residential)
"Devices that use B-Vents should be outlawed. When I started installing boilers and furnaces back in 1994, all I wanted to install was condensing units, but I noticed some problems with reliability and real world performance advantages. For most…"

Bill Bradbury replied to terry nordbye's discussion insulation in the group Best Practices (Residential)
"Terry, I have never seen it. I took apart a house with a badly leaking roof, the wing wall that was uninsulated had a 6' tall bees nest with 1000's of bees, the next bay over was dense-packed cellulose and had 0 bees."
Apr 12, 2012
Bill Bradbury replied to Sean Lintow Sr's discussion Drilling B-Vents in the group Best Practices (Residential)
"Come on Ted, That was a bit heavy handed, even for you! "
Apr 12, 2012
Bill Bradbury replied to Ronald L. Stevens's discussion How to help new energy pros migrate into our new career as fresh students right out of class
"Some of the most knowledgeable trades people I know volunteer for Habitat for Humanity. You could help your community while gaining valuable OTJ experience and make connections with hi integrity contractors. To really "get it", you have to…"
Apr 2, 2012
Bill Bradbury replied to Tom Mallard's discussion Applied Passive-solar Structural Design
"Hi Tom, I looked over your plans a little closer this morning and there are a couple other comments that I would like to make. PVC is not a good choice for water pipes, since it has a low heat transfer coefficient, is prone to fracture spirally if…"
